Question

A student spend 1/2 of his money on books.Also he spent 1/4 of his money on box.If he still had rs:50,howmach money did he have in total

Answer 1

amount spent on books = 1/2

amount spent on box = 1/4

amount left = 50

let the total amount be 'x'

then

x - 1/4(x) - 1/2(x) = 50

x - x/4 -x/2 = 50

lcm = 4

{4x -x(1) - x(2)}/4 = 50

{4x -x(1) - x(2)} = 50 * 4

{4x -x(1) - x(2)} = 200

4x - x - 2x = 200

x = 200 = total money
